Subject: [PATCH] Update minimum required CMake version to 2.6.3.

Verified build with CMake 2.6.3, failed with 2.6.2.

We need 2.6.3 for "unset" (unknown command in 2.6.2 and earlier).

CMake 2.6.2 also fails when parsing nested brackets in logical
expressions like the following one:

  if((NOT APPLE OR OPTION_APPLE_X11) AND NOT WIN32)
